BOISE — Senate President Pro-Tem Brent Hill looked out at the chamber of Idaho senators, shocked at their silence.

He had just asked for debate on HB 578 — a bill that would require some out-of-state retailers to collect and remit Idaho’s sales tax on online purchases — but was met with none.

The bill, brought by Rep. Lance Clow of Twin Falls and carried on the Senate floor by Sen. Jeff Siddoway of Terreton, passed the Senate 30-4 Tuesday. It will now be sent to the governor’s desk to await a signature.
